A CORPORATION OF ILLINOIS.

SEAM FOR SEWED ARTICLES.

Specification of Letters Patent. Application filed July 23,1902. Serial No. 116,635.

Patented Feb. 13, 1906.

To all whom, it may concern:

Be it known that I, J AMES LORENZO PAT- TERSON, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Seams for Sewed Articles, of which the following is a description, reference being had to the accompanying drawings and to the letters and'figures of reference marked thereon.

My invention relates to an improvement in seams for sewed articles, and especially to a seam for use upon ladies skirts, to give the same the appearance of cording in which the stitches are practically hidden.

The invention comprises a seam composed of two pieces of fabric whose abutted folded edges are united, preferably, by a line of straightaway stitches. One of the pieces of fabric adjacent the fold is raised or ribbed, and two lines of stitches are passed down upon either side of the ridge or rib, one of which is preferably that is, between the two folded abutting edges.

Finally, the invention consists in the matters hereinafter described, and referred to in the appended claim.

In the accompanying drawings, which illustrate the invention, Figure 1 represents a cross-section of a seam constructed in accordance with my invention, and Fig. 2 is a plan view of the same.

In the drawings, A A represent two pieces I of fabric whose abutting folding edges are united by a line of stitching 1. Upon one piece of the fabric A, adjacent the fold, a rib or ridge is formed, and passed down through the fabrics are two lines of stitches 2 3, of which the line 3 preferably passes down practically in the line of the seam* in the line of the seam or very closely adjacent to the folds. These lines of stitches 2 3 are secured upon the under side by concatenating locking-threads 1.

The manner of making the seam is as follows: The two pieces of fabric A A are superposed and the line of straightaway stitching 1 secures them together adjacent their edges. The fabrics are then folded out flat and passed through an air cording-machine of the Union Special type, such as illustrated in application of Russel G.-Woodward, Serial No. 671,283, patented July 12, 1904, No. 765,120, and the two lines of stitching 2 3 pass down upon either side of said rib or ridge, preferably the stitches 3 passing down substantially in the line of the abutting folded edges, although they may be slightly within the folded edge of the fabric A, in which event they would serve to strengthen the seam.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A seam composed of two fabrics having abutted folded edges, with a line of stitching uniting the same at the fold one of said fabrics being provided with a rib orridge,pressed up out of the body of the fabric, and lines of stitching passed down upon the opposite sides of said rib or ridge,with lockingthreads for securing the lines of stitching together on the under side, thus permanently fixing said rib or ridge; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES LORENZO PATTERSON.
